説明

Among Friends is a decentralized peer-to-peer betting and social coordination platform built on Mantle, designed to enable trustless wagers between friends without bookmakers, oracles, or custodial intermediaries. The platform operates as a social terminal, allowing users to formalize informal agreements such as sports bets, personal challenges, and future predictions into enforceable smart contracts with guaranteed on-chain settlement.

Use Cases

  • Social Betting: Friends wagering on sports matches or live events without relying on centralized bookmakers.

  • Challenges & Commitments: Fitness goals, habit tracking, or skill-based challenges with financial incentives.

  • Predictions: Peer-to-peer bets on future outcomes such as crypto prices, market movements, or public events.

  • Custom Agreements: Any informal agreement that requires neutral enforcement and transparent settlement.

Core Features

  • Non-Custodial On-Chain Escrow: ERC-20 stakes are locked directly in smart contracts, eliminating counterparty and platform risk.

  • Consensus-Based Resolution: Outcomes are resolved through participant voting, removing dependency on oracles or centralized adjudicators.

  • Permissionless Participation: Anyone can create or join a wager using a supported token and a connected wallet.

  • Automatic Settlement: Once consensus is reached, payouts are executed programmatically with no manual intervention.

  • Terminal-Style UX: A structured, multi-step flow for creating, joining, voting, and resolving wagers with full transparency.

Advantages

  • Trustless by Design: No house, no custodians, and no reliance on external data providers.

  • Flexible and Composable: Supports multiple wager types and can evolve into oracle-based or DAO-governed resolution models.

  • Mantle-Native Efficiency: Low fees and fast finality enable frequent, small-stake social interactions.

  • Transparent and Verifiable: All wager logic, votes, and payouts are recorded on-chain and auditable.

Each wager is deployed as an on-chain contract instance with non-custodial ERC-20 escrow, ensuring all participants retain cryptographic guarantees over their funds until resolution. Participants join by staking an agreed amount, after which outcomes are determined through consensus-based voting by the involved parties. Once voting conditions are met, the contract automatically resolves the wager and distributes payouts proportionally, eliminating manual enforcement, disputes, or counterparty risk.

The platform leverages Mantle’s low transaction fees and fast finality to support frequent, small-stake interactions while maintaining a clean, terminal-inspired UX optimized for clarity and transparency.

Among Friends demonstrates how social trust and financial settlement can be encoded directly into smart contracts, creating a flexible, permissionless alternative to traditional betting systems and centralized platforms.

ハッカソンの進行状況

During the hackathon, Among Friends progressed from concept to a fully functional, deployed decentralized application on Mantle Testnet. The core smart contract architecture was designed and implemented to support non-custodial ERC-20 escrow, participant management, consensus-based voting, and automatic payout distribution. Contracts were deployed and verified, enabling real on-chain wager creation, participation, and resolution. On the application layer, a complete end-to-end user flow was built, including a multi-step wager creation builder, bet discovery and joining by ID, a terminal-style wager interface, and transaction progress feedback. Wallet-based authentication, token approval optimization, balance checks, and on-chain state synchronization were implemented to ensure a smooth and reliable user experience. Metadata handling was integrated using IPFS for off-chain wager details, while Mantle’s low fees and fast finality were leveraged to make frequent, small-stake interactions practical. By the end of the hackathon, the project delivered a working demo showcasing real wagers, live voting, and automatic settlement on Mantle, demonstrating both technical execution and clear product viability.
